The annual global-construction waste is projected to exceed 2.2-billion-tonnes by 2025 (U.S.-Environmental-Protection-Agency, 2021). This waste accounts for over 30% of CO2 emissions which has severe consequences for climate-change. This waste not only has a negative impact on the environment, but it also represents a missed opportunity to recycle-or-reuse valuable materials. The construction-demolition-and-excavation industries are responsible for generating around 60% of the UK's waste, with demolition being a major contributor within the construction industry. Findings suggest construction-and-demolition(C&D) waste amount to over 100 million tonnes annually (Hughes & Salvidge, 2018), and in 2020 alone, the UK generated over 53.6 million tonnes of non-hazardous C&D waste (UK statistics on waste, 2020).Reusing materials have a significant impact on reducing embodied carbon emissions, with potential savings of up to 95% compared to purchasing new products. To address this issue, the UKGBC has implemented a Circular-Economy Guidance for Construction Clients, which includes "Maximise Reuse" as one of its guiding principles (UKGBC, 2019), alongside other policies aimed at reducing waste. The rising awareness of the built-environment sector's impact on the climate has also led to increased pressure on developers to reduce waste generation, and one of the measures implemented to achieve this is Pre-demolition audit.Pre-demolition audit is conducted to help maximise reuse & recycling of materials. While demolition is often necessary for new development and revitalization, it is important to consider the impact on the environment and take steps to minimize waste-generation. Pre-demolition audit is required to support the circular economy statement as part of the planning stage of redevelopment, to promote sustainable building practices, and identify opportunities for cost-savings. However, it is generally a time-consuming process requiring several weeks to complete, depending on the project size. Despite the benefits of pre-demolition audit, the long-time required is often seen as a burden by developers/clients who may view it as a delay in the construction process. This can lead to the temptation to skip this important stage, which can inherently have significant consequences for the environment & economy.This project (APAIR) is aimed at automating the pre-demolition audit process and improving the reusability of construction materials before demolition. APAIR aims to streamline the pre-demolition audit process, by using advanced machine-learning algorithms. it can quickly identify the reusable materials present in a building before demolition. This information is then used to determine which materials can be reused-recycled-repurposed or disposed. APAIR has the potential to revolutionize the demolition-industry.

预计到 2025 年，全球每年建筑垃圾将超过 22 亿吨（美国环境保护署，2021 年）。这些废物占二氧化碳排放量的 30% 以上，对气候变化产生严重后果。这种废物不仅对环境产生负面影响，而且还错失了回收或再利用有价值材料的机会。建筑、拆除和挖掘行业产生了英国约 60% 的废物，其中拆除是建筑行业的主要来源。研究结果表明，每年建筑和拆除 (C&D) 废物量超过 1 亿吨（Hughes & Salvidge，2018），仅在 2020 年，英国就产生了超过 5,360 万吨无害 C&D 废物（英国废物统计数据，2020）。重复利用材料对减少隐含碳排放量具有重大影响，与购买新产品相比，可节省高达 95% 的碳排放量。为了解决这个问题，UKGBC 实施了建筑客户循环经济指南，其中包括“最大化再利用”作为其指导原则之一（UKGBC，2019），以及旨在减少浪费的其他政策。人们越来越意识到建筑环境部门对气候的影响，也导致开发商减少废物产生的压力越来越大，而为实现这一目标而采取的措施之一就是拆除前审核。拆除前审核的目的是帮助最大限度地重复利用和回收材料。虽然新的开发和振兴往往需要拆除，但重要的是要考虑对环境的影响并采取措施尽量减少废物的产生。作为重建规划阶段的一部分，需要进行拆除前审计来支持循环经济声明，促进可持续建筑实践，并寻找节省成本的机会。然而，这通常是一个耗时的过程，需要几周的时间才能完成，具体取决于项目的规模。尽管拆除前审核有好处，但所需的长时间通常被开发商/客户视为负担，他们可能认为这是施工过程的延误。这可能会导致人们跳过这一重要阶段，这本身就会对环境和经济产生重大影响。该项目 (APAIR) 旨在实现拆除前审核过程的自动化，并提高拆除前建筑材料的可重复使用性。 APAIR 旨在通过使用先进的机器学习算法来简化拆除前审核流程。它可以在拆除前快速识别建筑物中存在的可重复使用材料。然后，该信息用于确定哪些材料可以重复使用、回收、重新利用或处置。 APAIR 有潜力彻底改变拆除行业。
